- TDM slot:
- This specifies audio DAI's TDM slot.
- TDM slot properties:
- dai-tdm-slot-num : Number of slots in use.
- dai-tdm-slot-width : Width in bits for each slot.
- dai-tdm-slot-tx-mask : Transmit direction slot mask, optional
- dai-tdm-slot-rx-mask : Receive direction slot mask, optional
- For instance:
- dai-tdm-slot-num = <2>;
- dai-tdm-slot-width = <8>;
- dai-tdm-slot-tx-mask = <0 1>;
- dai-tdm-slot-rx-mask = <1 0>;
- And for each spcified driver, there could be one .of_xlate_tdm_slot_mask()
- to specify a explicit mapping of the channels and the slots. If it's absent
- the default snd_soc_of_xlate_tdm_slot_mask() will be used to generating the
- tx and rx masks.
- For snd_soc_of_xlate_tdm_slot_mask(), the tx and rx masks will use a 1 bit
- for an active slot as default, and the default active bits are at the LSB of
- the masks.
- The explicit masks are given as array of integers, where the first
- number presents bit-0 (LSB), second presents bit-1, etc. Any non zero
- number is considered 1 and 0 is 0. snd_soc_of_xlate_tdm_slot_mask()
- does not do anything, if either mask is set non zero value.
